Alyseum

Alyseum is a Belgium-based manufacturer of modular synthesizer modules and other connectivity products.

MS-812, Ethernet to CV and digital converter
The MS-812 is the first of Alyseum's modular products range. It is available in Eurorack (18HP width) and Frac (4.5") form fit.

The product is dedicated to users wanting to control high-resolution CV/digital from computer-based applications. It ensures a low latency that Ethernet offers inherently.

The actual transfer format is CopperLan, whose messaging handles MIDI transparently. It is also via CopperLan that the MS-812 is editable. There are over 200 parameters offered to the user. The editing is done with the CopperLan Manager, a cost-free application available for MAC, WinXP, Vista, Seven and iPad. Moreover, user-chosen parameters can be controlled via a freeware iPhone CopperLan mini-controller application.

The MS-812 can issue notes, controls, gates, triggers, clocks and many derived signals.
 * Any of the 55 possible analog signals can be mapped to the 8 CV jacks.
 * Any of the 94 possible digital signals can be mapped to the 12 Digi jacks.

Musical features
 * Dedicated blue LED for note messages
 * Up to 7 dedicated mono sections - For every section:
 * Voice priority: to the lowest, highest, or last note played
 * Voice/play buffer to allow "analog" play techniques such as trills with multiple fingers.
 * Analog-like (exponential) portamento
 * Transposition in a range covering over twenty (yes 20!) octaves in one go (means deep down to LFO)
 * Pitch-bend is implemented in 16-bit (14-bit for MIDI sources) with separate positive and negative range settings
 * Handles both attack and release velocity
 * Learn function to map any MIDI controller
 * Gain, polarity and offset on all control voltages
 * Value comparator with independent events for high and low thresholds
 * Gating and triggering with adjustable polarity
 * Polyphonic section
 * Same features as the Mono sections
 * Can be set from 1 to 8 notes - can act as an eighth Mono section
 * Clock section - Receives up to two clocks simultaneously (even from MIDI!) - For each incoming clock flow:
 * Dedicated clock receive red LED
 * Tick, Reset, Status (on/off) and Fill-in signals
 * Conversion to DINSync-24, via a simple adapter
 * Multiple simultaneous clock divisions on any number of jacks
 * Clock polarity adjustable
 * Clocks can generate pulses or toggling signal
 * Drum oriented section (ignores release velocity)
 * Drum notes can be mapped into one of 8 octaves
 * Up to 12 Drum gates and 8 associated velocity signals
 * Velocity offset and gain control
 * Additional unified velocity signal for global accent
 * Direct Jack Control section
 * Used for control via dedicated computer applications or simple knob to CV mapping
 * Bypasses all data processing

Other features
 * Preset management
 * 32 user presets with recall via MIDI
 * Presets can be named
 * Electrical pulse length setting (for older machines)
 * Global LED polarity control, independently of the signal on the jacks
 * Firmware update via Ethernet

Editing features
 * Editing is done via any Windows/Mac/iPad
 * Parameters are shown with explicit lists, names and data types, all in high resolution
 * Parameters are themselves controllable in real time

Try the MS-812 before you buy
You can evaluate the MS-812 thanks to an emulation program.

In the demo, CV outputs are reflected on bar-graphs while the digital outputs act on drawn "LEDs"; besides that, the entire functionality of the real product is there.

Demo procedure:
 * Download the MS-812 from Alyseum's website
 * Download the CopperLan package from CopperLan's website
 * First install the CopperLan package (one click procedure)
 * Then start the MS-812 demo application
 * There is no network setting of any kind since CopperLan is self-configuring by design.
 * From the CopperLan Manager connection tab, you can establish connections from existing MIDI applications to the MS-812.
 * From the CopperLan Manager edition tab you can access the MS-812 parameters.

If you want to play with high-resolution control, you can also use a small CopperLan application that emulates a joystick.
